Making quad rail power and highly advanced power supply design available at a popular wattage, the HCG-750features special High Current connectors andheavy-dutycabling, earning it NVIDIA® SLI™- Ready and ATI™ CrossFire™ certifications. At the same time theHCG-750is also 80 PLUS® Bronze certified for efficiency, and features active PFC with a swift, quiet 135 mm double ball bearing fan so you know you’re getting not only High Current, but also high efficiency and excellent cooling. If loads of power, High Current engineering and exceptional efficiency are what you’re after, theHCG-750is the perfect PSU for you.
The connectors and power specifications of the HCG-750PSU are all compatible with ATX12V v2.3 and EPS12V v2.91 specifications. TheHCG-750features Universal Input, which automatically senses when you connect the power supply to any AC power source between 100~240V without setting a voltage switch. This power supply also features Active Power Factor Correction (Active PFC), which improves the power factor value of the power supply by altering the input current wave shape, helping to power transmission across the grid.
A variety of industrial-gradesafety circuitry will help protect your computer: OTP (Over Thermal Protection), OVP (Over Voltage Protection), SCP (Short Circuit Protection), OPP (Over Power Protection), and OCP (Over Current Protection). Sometimes the PSU will “latch” into a protected state. You will need to power off the PSU and clear the fault before it will function again. There are nouser-replaceablefuses in yourHCG-750.
80 PLUS® CERTIFICATION
80 PLUS® certification is the most widely recognized independent standard in power supply efficiency. An 80 PLUS® certified power supply uses less energy and generates less heat to stay cooler, run quieter and last longer. The HCG-750has been 80 PLUS® Bronze certified to be at least 82% efficient at a wide range of operating loads; this will lower your operating costs and help protect the environment.
The HCG-750power supply distributes power on separate rails. Some rails require a minimum load in order to run. To see the output capacity and regulation for each different voltage, see Table 1. A list of all available power connectors can be found in Table 2.

1. Install the HCG-750PSU into either the top or bottom of your case with the four screws provided. Refer to your case manual if you are unsure where the power supply should be installed.
2.Connect the 24(20 + 4)-pinmain power connector to your motherboard. If your motherboard uses a20-pinconnector, detach the4-pinattachment on the24-pinconnector.
Note: The detachable 4-pinsection cannot be used in place of a4-pin+12V connector.
3.Connect the 8(4 + 4)-pinconnector for the CPU.
Note: Please also refer to your motherboard user’s manual for any special instructions.
4.Connect the PCI-Econnector(s) to your graphics card(s).PCI-Egraphics cards use different amounts of power. For some, a single6-pinconnector is sufficient, while more powerful cards use multiple connectors, including the advanced8-pinPCI-Econnector. The8-pinPCI-Econnectors on theHCG-750can be used as either 6- or 8- pin connectors.
5.Connect all Molex/SATA connector(s) to your hard drives, optical drives (CD/DVD/BluRay™) and other accessories. Please note that some devices will use either the older 4-pinMolex connectors, while others will use the newer15-pinSATA connector.4-pinMolex connectors have two black wires, a yellow, and a red. The SATA connector has an additional orange power wire.
6.Connect your floppy drive if present using the supplied FDD connector shown in Table 2.
7.When you have all the connections secured, connect the AC power cord to the power supply AC inlet, making sure the use the heavy-dutycord supplied with yourHCG-750.
8.Turn the switch on the PSU to the “|” position.
